Benefits of technology

The present invention relates to a system and method for detecting the movement of an RFID tag in a specific area. The system includes a transmitting / receiving antenna, a tag reader / writer, and a detection frequency information obtaining section. The system can determine if the RFID tag is moving out of the area based on the detection frequency information obtained from the reading of the RFID tag in the area. The system can also determine the direction of movement of the RFID tag based on the results of the movement determination. The technical effect of this invention is to provide a system that can accurately detect the movement of an RFID tag in a specific area and determine the direction of movement.

Problems solved by technology

However, the conventional tag information processing apparatus has involved the following problem.
As a result, it is not possible to determine (a) which tag is being moved and (b) which tag is staying within the RFID tag-reading area.
That is, the conventional tag information processing apparatus has not been capable of selectively reading only (i) information of a tag of a parcel which is being moved out of an RFID tag-reading area or (ii) information of a tag of a parcel staying within the RFID tag-reading area.

embodiment 1

[0064]FIG. 1 illustrates a configuration of a tag information processing system, including a tag information processing apparatus, of the present embodiment.

[0065]A tag information processing system 1000 includes a tag information processing apparatus 10, a transmitting / receiving antenna 11, and a tag reader / writer 12. Note here that the number of targets to be dealt with by the tag information processing system 1000, i.e., the number of RFID tags 100 whose information is to be read in the tag information processing system 1000, is 1 or greater. In the present embodiment, a description is given for a case where the tag information processing system 100 deals with one (1) RFID tag 100. Note however that the tag information processing system 1000 can deal with also a plurality of RFID tags 100 each having different identification information.

[0066]The tag information processing apparatus 10 includes a receiving section 101, a detection frequency information obtaining section 102, a mo...

embodiment 2

[0151]A tag information processing system in accordance with the present embodiment makes it possible to estimate a direction (hereinafter may be referred to as a movement direction) in which an RFID tag is being moved, by making use of the configuration of the tag information processing system described in Embodiment 1.

[0152]FIG. 12 is a block diagram illustrating a configuration of a tag information processing system in accordance with the present embodiment. A tag information processing system 1001 includes a tag information processing apparatus 20, a first transmitting / receiving antenna 21, a first tag reader / writer 22, a second transmitting / receiving antenna 23, and a second tag reader / writer 24. Note that the tag information processing system 1001 deals with at least one RFID tag 100, as is the case with Embodiment 1.

[0153]The tag information processing apparatus 20 includes a first receiving section 201, a second receiving section 202, a first detection frequency information ...

Abstract

A tag information processing apparatus, including: a receiving section (101) for receiving read-out information of an RFID tag (100), the read-out information obtained through N reading operations (where N represents an integer equal to or greater than 2) carried out for an RFID tag-reading area; a detection frequency information obtaining section (102) for obtaining detection frequency information on the basis of the read-out information received by the receiving section (101), the detection frequency information indicating a detection frequency at which the read-out information of the RFID tag (100) is detected in the N reading operations; a movement determining section (103) for determining whether or not the RFID tag (100) has been moved out of the RFID tag-reading area, wherein, in a case where the detection frequency information obtained by the detection frequency information obtaining section (102) indicates that the detection frequency at which the read-out information of the RFID tag (100) is detected is low, the movement determining section (103) determines that the RFID tag (100) has been moved out of the RFID tag-reading area; and an output section (104) for outputting a result of the determination made by the movement determining section (103).

Description

TECHNICAL FIELD[0001]The present invention relates to (i) a tag information processing apparatus which processes information read from an RFID (Radio Frequency Identification) tag, and (ii) the like.BACKGROUND ART[0002]Conventionally, there has been known a method for managing, by using RFID tags, materials which are moved in and out via a plurality of points, the method including the steps of:[0003]registering the materials and data of IC tags attached to the respective materials in such a way that each of the materials and the data corresponding thereto are associated with each other;[0004]transmitting and receiving information on the materials and the IC tags corresponding thereto at times of the materials being moved in and out; and[0005]checking the registered information on the materials and the IC tags corresponding thereto at the times of the materials being moved in and out (for example, refer to Patent Literature 1).[0006]Patent Literature 1[0007]Japanese Patent Applicatio...
